Step-by-step explanation:
The duration of sinusitis, or inflammation of the sinuses, can vary depending on the cause and individual factors. Acute sinusitis typically lasts for about 2 to 4 weeks, while chronic sinusitis can persist for 12 weeks or longer. Symptoms of sinusitis may include facial pain, congestion, nasal discharge, and headache.
For example, sinusitis may occur as a result of a viral infection, such as a common cold, or a bacterial infection. In viral sinusitis, symptoms usually improve within a week or two as the infection resolves. Bacterial sinusitis may require antibiotic treatment and symptoms may take longer to resolve.
If symptoms persist or worsen, it is important to consult a healthcare professional for proper diagnosis and treatment.
